IMPROVEDMEANS FOR EXTINGUISHING GAS-LIGHTS.

. Specification forming part of Letters Patent No. 35,525, dated June 10, 186:2.V

To `1f/ZZ whom it concern.:

Be `it', known that I, `OLIVER S. JUDD, of

` New Britain, in the county of Hartford and State of Connecticut, have invented, made, and appliedto use a certain new and useful Improvementin Means for Extinguishing Gas- Lamps; and` I do hereby declare that the following is a full, clear, and exact description `of my said invention. reference being had toV the annexed drawings, making part of this specification, wherein- Y Figure l is a plan of my said invention, and Fig. 2- is an elevation ofthe same.

Similar marks of reference denote the samey parts. i a

The nature of my said invention consists in the employmentfof a spring, orits equivalent, applied to turn the cock in the pipe of a gas lamp to extinguish the light, said springbeing controlled by a clock-movement, so as' to shut 4Means have heretofore been devised for i `lightingand extinguishing lamps by electricity i, sary by relievngthe attendant of the labor of shutting off the gas. My device,n1oreover, is applied directly to the ordinary gas-cocks, and

` fis simple and cheap,involving no change in f the pipes or burners. y i

In the drawings, a represents any ordinary gas-burner.

a b is the cock.

c is a sector attached to the cock, from which a cord or chain passes to the wheel d on the i arbor e, that has a coiledspring, j", around it,

and r is a catch` or arm on e, taking a latchlever, g, on the fulcrum h. y y

i t is aolock-,movement that maybe provided with a dial and hands in the usual manner, or these may be dispensed with. k is a cam set on the arbor of the clock usually receiving the hour-hand, so that said cam revolves once in twelve hours, or the gearing of the clock may in twenty-four hours. An arm, Z, is provided from said cam k, whereby it can be moved upon said arbor and set to any desired place, the friction retaining the same in the posit-ion to which it is set. j

When the lamp lighter turns on the gas, the act of moving the cock b winds up the spring f, vandturns the arm r, causing it to'catch under the lever-latch g, said lever being lifted by the -arm and falling by itsown weight or by a spring, 0,' and in this position the parts re- 1nainas seen in Fig. 2, until the cam k, acting -on the lever g, releases the arm r, when the spring f turns the cockl shutting, off the gas.

is a block or stop for the sector c to take against, t0 prevent the spring moving the cock too far.

It will be evident that the arm or hand Z of the camV 7c indicates to the attendant how long thegas will burn by observing the number of hourson the dial between the point indicated by said hand and the point at which the cam The clock-movement may be placed below the gas-burner in the post,if necessary or more convenient.

What I claim, and desire to secure by Letters Patent, is-

The sector c, applied to the gas-cock, and

moved by a spring or its equivalent to shut off the gas when thelatch-lever gis disconnected f by the clock mechanism, as and for the purposes set forth. Y

In witness whereof I have hereunto set my signature this 28th dayV of March, 1862.

OLIVER s. JUDD.
